Algorithm::Accounting provide simple aggregation method to make log accounting easier. It accepts data in rows, each rows can have many fields, and each field is a scalar or a list(arrayref).

The basic usage is you walk through all your logs, and use append_data() to insert each rows, (you'll have to split the line into fields), and then call result() to retrieve the result, or report() to immediatly see simple result.

You may specify a filed_groups parameter (arrayref of arrayref), and Algorithm::Accounting will account these fields in groups.

Notice you'll have to give a list fileds first, the append_data() depends on the number of fields to work properly.
